What is the answer to this polynomial expression question?
For the polynomial:
f(x) = -2x^3 - 2x^2 + 7x - 25
x ---> - ∞ f(x) ------> ∞

Look at the first term:
As x is infinately negative, x³ will continue to be negative.
Multiply that by -2 and now it's positive.
So the limit of f(x) as x approaches negative infinity would be positive infinity.
So that statement is true.
